Input

4 inputs» Triggers

› Voltage up to 24 V Signals

» RS-232By the way:Opto isolatorFor new EXO & SHR series

IOMUX

IOMUX

Switch Matrix Input to

» Debouncer to› Pulseloop0 to

Output2 open drain› Pulseloop1 to

•UART toOutput3 RS-232

by the way: Inverter and set-to-one

Before and after every IOMUX module

Invert signal» Trigger interpretation can

also be inverted Set signal to „1“

» Just turn the signal ON» or turn it OFF by inverting it at the same time

Debouncer

Eliminates „ringing“» Glitches: spikes, overshoots

1. Masking the input for a period of time

2. Comparing the signal after the period

Prescaler

Masking every 2nd, 3rd, 4th, and so on

by the way: high low trigger

Schmitt Trigger

Programmable values that have to be crossed for a trigger interpretation true

Sequencer

One trigger signal results in:» Up to 16 intervals with individual:

› Total length› Exposure time› PWM frequency› Up to four strobe outputs with individual

• Intensity• duration

Sequencer

One trigger signal:

by the way: PWM

Pulse Width ModulationIntegrated in the Sequencer

regulate the intensity of an LED light» Extend LED life cycle

Set base frequency period length» for each sequencer interval

Set duty cycle Δ in %» for each sequencer output

by the way: PWM

25 % intensity

50 % intensity

75 % intensity

Pulseloop

Four individual pulse generators» Set delay and duration time

Pulseloop

Four individual pulse generators» Set number of loops

An individual PWM

Pulseloop

Camera cascade

» Exposure internal cam1» Exposure external cam2» Trigger cam3

Pulseloop

Wait for second shoot

After first aquisition software demands a second exposure

Pulseloop
